The master thesis describes the development of digital control of an analog parametric equalizer or sound processor which is intended for music processing in the process of creating music. The history of recording music from a mechanical to an electrical process is presented, where such a way of producing or recording music as we know it today is formed. This means that the use of historical analog equipment is today an integral part of musical genres and is therefore still used. In order to make its usage easier from what the digital equipment today offers, that is the possibility of automatic adjustment or control without manual intervention, it is necessary to appropriately automate such devices without any perceptible impact on the audio signal. This was achieved by replacing all manually controlled elements with electrically controlled ones. In this case, manually controlled elements remain the same in their appearance (the appearance of the device remains the same) and serve only to detect positions in the possibility of manual use and no longer interfere directly with the analog signal.
The necessary electronic assemblies were developed and added to the existing device and were successfully upgraded into an automated device that is controlled via a communication link with a personal computer. Anticipated problems and their solutions are mentioned, as well as unforeseen problems and solutions. Finally, potential improvements and reductions that would be possible in the future are considered.
